Like us on Facebook. If your input-output voltage is too large then it will heat up a lot more quickly. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at I am notifying you, because this is a registered package, so, please arrange to have someone at home to sign for the delivery. Lm78S05 and you’re going to need a heatsink. Hero Banned Mar 7, If you buy some item, and order 4 lots.

On the other hand, if you’re supplying it from a 20v supply, that’s a 17 volt drop across the regulator and at 1a, 17 watts of power dissipated. LMKModified Item: The chances are that your LM is fine but you haven’t dataaheet it on a decent heat sink.

Great seller with very good positive feedback and over 50 ratings. All of them require a heat sink!

Besides that, a usually reacts “negatively” to overcurrent spikes like that and tries to shut down unless you’ve hung a ridiculously-large amount of capacitance on its output.

Each bidding lot is for 2 pcs Net weight approx: Thanks for you looking. Even the LM will shut down datashet if you try powering something that takes a couple of amps at 5v if you’re using a 30v input.
